i suggest checking the lamp. find you owners manual and go through the steps to "replace the lamp" if it is popped and you can see little pieces moving around inside than contact toshiba and they will send you a replacement with credit card numbers of course.

Hi John,
If you are hearing this noises,that's your Color Wheel.
The reason fot that is because your color wheel spins 5000rpms(revolution per minute) and something that modifies the balance if the disc can cause different things.Unfortunately in order to check if your color wheel is working properly you need to open your TV and physically check out.
Grinding= Most probably the color disc is broken and you need to replace it.
Spinning / Buzzing = The bearing of the wheel is loose and is loosing its balance,eventually it will brake.
The best thing to do is to take the color wheel out and spin it ,if you feel that the disc kind of wobbles or doesn't spin smoothly you have to replace it.
You can check DM they have very good prices
